摘要
在中东,绝大部分都是沙漠地区,在沙漠地区修筑高速公路只能利用砂做填料。砂质松散渗水性好、无粘聚性,内聚力小,抗剪能力差,在外力作用下易产生位移,且沙漠中风沙大,在施工过程中易于遭受大风吹蚀和砂埋,影响路基的压实质量和边坡稳定,可能致使修筑公路无法运营。本文结合沙漠地区高速公路的填砂路基的施工与防护,通过研究路基的填筑工艺,提出了相应路基的施工要点。
Highway construction can only use sand to fill because a large part of Middle East is made up of desert.The feature of sand has good water permeability,a little cohesion, and worse shear resistance.Therefore,the sand is easy to make displacement under the external pressure.Moreover,the erosion and burying of the heavy sand-wind is also easy to influence the quality of the roadbed compaction and slope stability.In this article,the writer gives the corresponding points of roadbed construction through researching the technique of filling work with the construction and protection of the sand embankment.
